Comparing the Slice to the Port Runner, I think the Slice looks a bit better overall... especially the stem/handlebar. They are definitely similar, but not the same. Is that worth the premium they appear to be charging?
Probably not... unless the bike comes with extras we don't know about. One thing of note, the Slice weighs a few pounds less than the Port Runner (though the Port Runner includes a rear rack which might be the cause of the extra weight).
Anyway... always happy to see a new brand. I think their main competition is Citizen and Downtube and they should price the Slice accordingly. That said, that mini-velo looks very nice, much better than the folders.
